If you are getting started with BIOS or EEPROM chip programming, the EZP2023 programmer is a popular entry-level tool. This guide explains what comes in the box, how it works, and common mistakes beginners should avoid.
What Is the EZP2023 Programmer?
The EZP2023 is a USB-based EEPROM and BIOS chip programmer commonly used for laptop BIOS recovery, printer EEPROM flashing, and SPI flash programming.
What Comes Inside the EZP2023 Box?
EZP2023 Programmer Unit
The main device connects to your computer via USB and contains the chip programming socket.
Adapters for Different Chip Sizes
The box includes SOIC8 adapters and a 1.8V adapter, which is essential for low-voltage BIOS chips.
SOP8 Test Clip
This clip allows in-circuit programming without removing the chip from the motherboard.
USB Cable and Software
The programmer connects via USB and uses dedicated software for reading and writing chips.
Correct Chip Placement
Always place the chip in the upper section of the main socket. Incorrect placement is one of the most common beginner errors.
Chip Detection: Automatic vs Manual
Automatic Detection
Most 25-series chips are detected automatically when clicking the “Test” button.
Manual Detection
24-series chips often require manual selection of manufacturer and chip model.
Reading and Writing BIOS Chips
Backup First
Always read and save the original BIOS file before writing new data. This backup is critical.
Writing the BIOS
Load the BIOS file and use the Write or Auto function to program the chip.
Common Beginner Mistakes
- Skipping the 1.8V adapter
- Wrong chip orientation
- Not saving BIOS backup
- Assuming all chips auto-detect
